Biventricular hydrocephalus secondary to aqueductal developmental venous anomaly

Developmental venous anomaly (DVA) is the most common type of intracranial vascular malformation. These lesions are benign and are considered to be non-pathological variants of normal deep parenchymal veins. Although most of them are asymptomatic, a small subset of them located in aqueductal region have been reported to cause obstructive hydrocephalus. The authors present an interesting case of biventricular hydrocephalus secondary to a DVA located on the proximal aqueduct in an adolescent patient. This case is discussed with in corroboration with current literature and management recommendations.
